The DD192 is a self-contained, single slot AXIe 3.1, 192 channel mixed-signal digital subsystem. Each DD192 has four sequencer controllers with pattern generators, and integrated timing generators connected to integrated pin electronics. The DD192 pin card can operate as 4 independent 48 channel sub-systems, synchronized as 2 independent 96 channel sub-systems, synchronized as an independent 192 channel subsystem, or synchronized with other pin cards controlled by a separate Digital Synchronization Module provided on the System Module installed in the system backplane.
